WoWInterface - using the same frame over and over again?

so, i'm wondering how i can make a button working like a tab, so that when you click it all new for example buttons will appear, and the others will disappear.

guess i kinda want to know how to make something kinda like the cosmos config frame, a list with addons, and when you click you get you get options for only that addon.

so pretty much, How do you change the frame layout with the click of a button?

i'm very new to xml, but i thought maybe you could put all the buttons/checkboxes/texts in the window, and then when you click a button to change "tab" it would do something like;

Code:

if (id == "2") then

button1:Hide();

button2:Hide();

button3:Show();

text1 = "";

text2 = "Button2:";

end

but is this really the easiest way?

thanks, i know i suck at explaining...
